Answer:
<h2><u><em>
y = 70°</em></u></h2>
Step-by-step explanation:
x = 35° (opposite agles)
y = 180 - 35 - 75
y = 70
-----------------------
check 35 + 75 + 70 = 180°
the answer is good
I think what you had was correct if you are talking about 17
Because this is a triangle, all three angles put together equals 180 degrees.
We can add the angles together and set them equal to 180 to solve for the value of y.
y + y - 12 + 56 = 180
Combine like terms.
2y + 44 = 180
Subtract 44 from both sides.
2y = 136
Divide both sides by 2.
y = 68
<u>The value of y is equal to 68 degrees.</u>
Answer:
Step-by-step explanation:
A polynomial is a perfect square if has the form:

Its factored form is
.
We can obtain examples by taking any value of a and b.
For example:
anb
.
Thus we obtain a polynomial that is a perfect square:


This is the solution to your equation.
